Jain dharm ke anusar, Rushabhdev Bhagwan (jo ki pehle Tirthankar hain) aur Shreyans Kumar ke beech ka sambandh ek ati pramukh ghatna se juda hai. Jab Rushabhdev Bhagwan ne apna rajya-tyag karke diksha li, to unhone bahut samay tak kuch bhi ahar nahi liya tha (bahut bhav tak bhookhe rahe). Us samay Shreyans Kumar ne hi unko pehli baar ahar — Ikshu Ras (ganna ras) — ka dan diya tha, jo "akhinchan pratyaksh ahar daan" ke roop me jana jata hai.

Jain granthon ke anusar, Shreyans Kumar pichhle anek bhavon se Rushabhdev Bhagwan ke prati bhakti aur seva bhav rakhte the. Lekin, kitne bhav ka sambandh tha, iska vistrit varnan Jain sahitya me spasht nahi milta. Lekin yah jarur kaha gaya hai ki Shreyans Kumar ko apne pichhle janm ki smriti prapt ho gayi thi, jis karan unhone sahi vidhi se Bhagwan Rushabhdev ko ahar diya.

Saaransh: Jain sahitya me Shreyans Kumar aur Rushabhdev Bhagwan ke sambandh ki bhavna aur purva-bhav ki katha milti hai, parantu kitne bhav ka sambandh tha, iska vishesh varnan nahi milta.
